  1. R value is the correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatterplot. The value of r is always between + 1 and − 1
  2. SBP systolic blood pressure, DBP diastolic blood pressure, HTN hypertension, ABPM ambulatory blood pressure monitoring, PWV pulse wave velocity, Cr creatinine, GFR glomerular filtration ratio, LVMI left ventricular mass index, CIMT carotid intimal thickness, ABI ankle-brachial index
  3. *Statistically significant difference (p < 0.05)
